Millions of Canadians take for granted that dialing 911 will let then access emergency services. But that’s not true in all parts of the country, and it may vary if the caller has a cell phone or a VoIP phone.

That’s why Canadians dump their landline phones for mobile devices, the Canadian Radio- television and Telecommunications Commission (CRTC) is gearing up to study the future of the country’s 911 service.

“Each year the 911 system is relied upon by thousands of Canadians during emergency situations, said Tim Denton, CRTC national commissioner who has been appointed inquiry officer by the commission for the formal review. “As telecommunications networks evolve and adopt new technologies, we have an interest in ensuring that the systems continue to meet Canadians’ needs.”

The formal review, set for 2014-2015, is being undertaken in light of the telecommunication’s ongoing evolution into next-generation networks based on Internet Protocol, according to a CRTC statment. The commission wants to know how public and private emergency services intend to use current and emerging technologies.

“I would encourage first responders, call centre operators and government bodies to share their ideas on how the 911 system could help them better respond to emergency situations,” said Denton.
